T450s Won't Boot After Battery Depletion

Q: T450s Won't Boot After Battery Depletion

Hi, I have a user at my company the let's her T450's battery rundown to empy... (She leaves it in sleep mode over the weekend and the battery dies) This happend a while back and I had to leave the laptop on charge all day, unplug the battery, hit the reset button on the back and then plug everything back in for it to start up again. Today, this issue happend again where the user ran the battery down to 0% and now the laptop will not boot up at all. I tried the following things noted below but all the laptop does is display three quick power button flashes when I plug the power cable into it. *Uplug the power cable and the battery. Hit the reset button on the back and then tried to power it on - Nothing*Uplug the power cable and the battery. Hold the power button down for 30 seconds and then tried to pwer it on - Nothing Going to leave it sit for a while but I do not think this is normal when someone runs the batter down to 0%. Has this happened to anyone else or is this laptop dead and I will need to send it in for service? Would like some thoughts on this... Thanks!

It sometimes takes an hour or so before the battery appears to begin charging from total empty, but usually it should boot fine regardless.Do these have the internal battery as well as an external battery?

Hi!Just switched from a macbook air to a T450S. Really like the computer in general but the battery time sucks for me. I use quite heavy applications but I still only get about one hour battery time (even though I have tweaked the battery optimization settings in the Power Manager. According to the specifications when I bought the computer, the batteries are of the type 6-cell litium jon 47wh.Is there anything I can do to make the battery life better?

Hi, I like that my T450s has 2 batteries. But the thing that bothers me is that the removable battery is drained first entirely prior to using the built-in battery. I've noticed that this increases the "cycle count" of the removable battery as essentially the battery has been completely used. In other laptops this is not a problem as they come with 1 battery and the cells are depleted uniformly.  This has only become a concern for me when I want to use the laptop for long hours without a charger. This would increase the cycle count of the removable battery if done on a daily basis. By doing so will I be ruining the battery life ?  Pls let me know, thanks.

A:T450s - How many cycles can the removable battery ...

Not sure, but I guess this is a bit by design, True the external is wearing more by having more cycles, but this also means that the internal one has a increased live time. The external one will be the first to wear, but is also the more easy one to replace .I already have 2 externals with my laptop.But I get your point and I'm curious about it too. Depleting a battery fully will wear a Li-ion more then not fully depleting it (if my study's where right that is). So it might be true that the less wear on the internal battery does not compare equally to the extra wear caused to the external battery.On the other hand, the extra wear might not be that great to worry about. And this dubble battery design does give us the awesome feature to hot-swap external battery's (which I use quite more that I thought I would).

Hi everyone, Just received my T450s. Installed the rear battery, then plugged in the power.  On my old T510 I have an indicator showing me when I have power hooked up, and indicates the charging status of my battery.  I don't see anywhere on the T450s chassis that indicates the status of the battery charge. The only thing I will see is the dot on the "i" on the top cover, flash when I connect power.  Surpised there isn't a status indicator. Peter

A:Just got my T450s - no battery charging indicator?

No, there is no charging indicator on the T450s. By popular demand, Lenovo added one back to the T460s.

My T450s has recently started discharging the internal battery first rather than the removable battery. I can't recall when this started to happen but I think it happened when I updated the BIOS to the latest version currently available. Anyone have any insight if this is an issue with other models and a fix? This is rather annoying. I have updated all of the other drivers with the System Update utility from Lenovo. Machine Type: 20BW

Hi all, My 2-year old Lenovo T450s is experiencing charging problems. If I plug in the battery charger, it starts charging for a second, it then stops, then the cycle starts again. Needless to say that none of the batteries (neither the built-in nor the external) charge properly. I tried to: (1) buy a new battery charger, (2) unplug the external battery leaving the internal plugged in, (3) unplug the built-in (internal) battery leaving the external plugged in. None of these solutions worked. I then unplugged both batteries and plugged the battery charger, and the laptop works. What do you think? Is it a hardware problem (perhaps related to the motherboard - I can't think of anything else)? Is it a software problem? Thank you in advance for your time! Best, Paolo

A:T450s only works on AC when battery is removed

I cannot be sure without seeing it, but I would guess motherboard charging circuitry.  I am assuming it will not charge while turned off.

Hello,
 
I got a T450s, brand new and everytime I am not plugged in (it's a laptop after all) the computer litteraly slows down to a point where it is unusable, a simple key (space, a letter, a number) will usually take 3-5 second and sometimes up to 20 seconds to register, no software is usable, CAD, video playback and authoring, completely useless when on battery. The thing is this is a laptop, I WILL use it on battery. That is despite me choosing high performance in the Lenovo power manager.
 
Anyway I can fix this?

I have read quite a few threads regarding Lenovo laptops requiring the battery to be disconnect to get the unit to turn on once it goes to sleep or is manually shut off.  I started having this issue on my 3 year old t450s about 3 months ago.  I disconnected the internal battery so that starting it up only involves removing the external battery. Is there a solution to this issue?  Of course I'd like to resolve it on this laptop but I'm even more concerned about purchasing an new t model laptop.  Love the laptop but am frustrated by this issue. Mark

After a long journey, both batteries in my T450s were flat, and this morning when I plugged in and booted up I got the message that "The battery installed is not supported by this system and will not charge".  True to its word, one of the batteries does not seem to be charging.  These are the original batteries which came with the laptop when bought new from Lenovo.  They have performed well since I received it, no problems to date, and no obvious reduction in performance.  How can I get the battery charging again? Thanks for your help.

Hello, My T540s (which just ran out of warranty ...) has a very weird issue : When I try to boot (clicking the power button), the fan starts turning, the keyboard's backlight turns on, but ... a second later (even before the Thinkpad logo shows up), the whole computer crashes and shuts down !Where it gets even more special is that from time to time (1 out of 1000) the computer boots normally, although giving me this warning :Secure Flash Authentification FailedCapsule Data is invalid_ I'm kind of lost right now, really don't know how to get that fixed. My friends think that my motherboard needs to be changed, but I really want to be sure before buying a new one (very expensive). I suspect a bug in the BIOS (recent update failed ?) ... What do you think ? Does anyone have or had the same problem ? Thanks for helping, Best, Sylvain E.K.  PS: Running Win7 64bit

One possibility: damaged USB port.  This was known to happen on some older T-series laptops.  Bent USB port pins would short power, causing the quick shutdown.

My year-and-a-half old T450s stopped booting up. Yesterday I was prompted for a Windows update and restarted the machine, as usual. After the update, I'm able to turn it on but it wont boot up. It shows the initial screen, with the "Lenovo" logo and won't proceed beyond.I tried taking out one battery and then holding the on/off button for 30 seconds, and also the emergency reset on the bottom, but neither changed anything. It simply won't go beyond the initial screen. Does anyone have any thoughts? Thanks in advance.

I think you are experiencing the same issue I have. If you notice after the Lenovo boot logo the display still stays on its just black, what it appears to be for me is a video failure after trying to update to windows 10 anniversary update. Try plugging in an external monitor and see if you get display, I did in my case.  Remove your hard drive and restart the PC, this should get the bios working again, go into your bios and disable secure boot so you can boot to a USB. Create a bootable USB 3.0 using a USB3.0 drive (formatted to NTFS) from Microsoft's site - https://www.microsoft.com/en-us/software-download/windows10/ Then goto repair my computer and choose rollback update, this will get you running again.  I have a p50 with Nvidia M1000M dedicated graphics, so I am still trying to figure out if this is a driver issue.

Hi,
I apologize for the inconvenience caused to you. You can follow the steps below:
Drain the residual power of your computer and recaliberate the battery by following the steps below:

Power off your computer. 
Remove all the external peripherals  (printers, scanners or any other USB device) connected to your computer.
Please remove the AC adapter and battery of your computer. 
Press and hold the power button of your computer for 10-15 seconds to drain the residual power. 
Release the power button
Keep the battery out for atleast 2 - 3 hours.
Then insert the battery and charge it overnight with the system powered off.
Insert the battery in and connect the AC adaptor.
Then power on the computer and see if it works.

If the issue still persists, you can update the BIOS of the computer.
Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.

Go into safe mode and go into msconfig and open the start up tab. What do you have in there? I would bet a lot of apps initializing on boot up. Keep only the apps you need like antivirus, firewall if there is one and any app you feel you need, but you only really need the above mentioned.

Here's a strange one:

On my Thinkpad R31, if it is plugged into an outlet, XP hangs on the splash screen, it even hangs on all safe modes. If I unplug it and let it boot off the battery, it boots perfectly fine. Once it's booted, I can run it off the adapter without a problem. The adapter charges the battery fine, and the battery holds a charge for a little over three hours of light use (web browsing, word processing).

Any ideas as to why it does this? I've tested it several times and it always boots without a flaw off the battery, but never off the adapter. I don't even know what to begin with here its so strange.

Thanks,

Joe

BTW, it stops at mup.sys when booting in safe mode.

Hello all,
I'm having an odd problem with a Tecra A6 I picked up recently to refurb in that it will not boot with a battery only: It boots only when the AC/Mains is also connected, however it will finish booting on battery alone (and runs fine) with the AC cord removed soon after pressing the power button. It's just on battery alone that I get no response from pressing the power on button (so the mains has to be attached at that very first stage or I get nothing at all).

Now I'm wondering if maybe its the voltage of the battery? It seems there are 2 options for this model, one at 10.8v and the other at 11.1v. With Windows loaded and Hardware Monitor running it reports the battery is at 0% wear level and charges up fully (so I do not think the battery is faulty), however it states the battery is running at *11.1v,* but the battery installed is in fact the *10.8v* model. Could that be preventing power on with battery only?

Further info on the model I have:
Tecra A6 PTA60E-0EJ013EN
CPU: Intel Core 2 Duo T7200 2.0 Ghz
2 Gb Ram.

Thanks in advance for any help on this one. Main thing I'd like to know is if I do need an 11.1v battery to run this model properly (and get it to power on) on battery alone. If the voltage makes no difference then I guess it must be an odd motherboard issue and I need not bother buying a new battery.

A:Tecra A6 does not boot with Battery only

Update on this one:

It appears the battery is likely faulty: I didn't leave it to run on battery only for long for initial tests so I thought I'd run it down, recharge, then see if that helps. I turned off all the power save settings then left it without the AC attached, however, in spite of reporting a full charge before the AC was removed ,the laptop switched itself off after only 5 minutes or so. On reboot (with AC attached again) the battery is reported as flat!

I have it on charge right now but the battery is *not* getting warm (it did the first time I installed it) so I figure either the battery or the mainboard is reporting the charge level wrong (this is a used battery btw, though it is a genuine Toshiba model, not a dodgy oem import).

Will have to buy another battery and see if the same thing happens (I'll know then if it's the motherboard), but in the meantime if anyone can let me know if the voltage does matter I would appreciate it.

I recently got this computer from a friend so I have no idea how long this has been going on. Probably why he got rid of it. I will plug in the power cord and try to boot with the battery in and nothing will happen. If I reach under the laptop and remove the battery and then try to boot up it comes on like normal. I can then put the battery back in but it makes no difference after that. The battery is completely dead. Does anyone know if this is a common problem with a bad battery or what. The computer is a Dell Latitude D630. If I knew that putting a good new battery in it would fix it I would without hesitation I just need to know if that is the problem or is it another glitch. If anyone knows the answer I would appreciate if they would pass it on. Thanks

Hi,

I replaced my laptop battery and once I installed the battery pack with a non-Toshiba compatible battery my laptop won't boot from the battery alone (Tecra S10-114) After the boot was done by AC adaptor (without fitting the battery), I installed it and the OS (WIN7 Professional) recognize and charge the battery regularly.

I can unplug the AC and the laptop working very well until there is enough battery power. Battery specs are almost similar than original (10.8V 5100mAh - PA3588U 1BRS) - 10.8V 5200mAh replacement for Toshiba battery PA3588U-1BRS, PA3356U, etc.

Can you help me to understand why there is just this boot issue and the rest working OK?
Do you have any solution?

Thanks
Luca

Maybe you should use a Toshiba original battery.
Get in contact with Toshiba ASP in your country who could send you a right and original part which would be compatible with the notebook.

We have a group of Elitepad 900 G1s that will not boot on battery.  The BIOS has been updated to the latest available as of 2/17/2017.  They will boot and run normally when the AC adaptor is attached, but as soon as you unplus the adaptor they shut down.  They will not boot at all without the AC adaptor, not even to the HP startup splash screen.  I installed the HP Diagnostic tools on one while it was on the adaptor and ran the battery check utility and it said the batteries were good, but needed calibration.  When I try to calibrate them, I get the message that your device does not support automatic calibration.  I also ran the powercfg.exe /BATTERYREPORT command and it said the batteries were good. How can I get the devices to actually boot when on battery only?

When on battery, my computer fails to boot. It displays Windows XP logo and loads things but when going into graphics mode it freezes (actually when Windows XP logo disappears it freezes). When on AC Power it boots ok. It looks strange to me. What could be wrong?

P.S.: Safe mode works even when running on battery. If I disconnect AC when XP is already loaded, it doesn't freeze. It works OK at first, but I must test it a little more to be sure. Computer is HP nc8430.

On first boot, there is a power drain from the source.
Sounds to me like you need a battery, how old is it?

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

A:Laptop battery not charging, battery not identified, 0% battery life

It sounds likely the charge circuit on the mainboard is damaged.  Contact Dell to have the mainboard replaced under warranty.

Hi guys. I have a T470 and after the latest Windows update I encountered a battery naming issue. Before the update batteries had proper order and were named accordingly: battery 1, battery 2, no surprises here. But after the update I noticed the order has changed to battery 0, battery 1 (attached pic below) Yeah yeah, I understand arrays start at zero but what is that? I was just wondering is it just me or you guys have the same situation going on with your batteries? Is there a way to change the order back to "normal"? .

The laptop is new. I am using Windows 10, nothing special: browsing, reading, etc. But CPU temperature is very often above 50 degrees. So, the fan turns on.

A:T450s: fan is on more often than not

Setting BIOS thermal management option to "balanced" helps very slightly.

I have a T450S laptop. It came with 8 GB of RAM (4 on the board and 4 GB SO-DIMM). I replaced the SO-DIMM with a Crucial 16GB one. When I look at the system information, it indicates that I have all 20 GB of RAM available. I recently asked the computer to do a relatively big, but not that big, processing job that took a long time (14 minutes). While it was crunching, I checked the resource monitor and it indicated that only 3.9 GB of the RAM were being used and that  ~16GB were available - but the extra 16 wasn't being used, just sitting there being available. When the processing completed, the resource monitor still says that 3.5 GB are being used with "regular" computing - so basically, nothing was different with the big job compared to just ordinary tasks. How do I make the computer use all of the memory that it has? I've looked all over for some sort of setting.?

According to this website: http://www.pugetsystems.com/labs/articles/Overview-of-M-2-SSDs-586/m.2 slot comes in different flavors (SATA III, PCI-E 2.0 x2, PCI-E 2.0 x4 and PCI-E 3.0 x4) I would like to know what is the supported protocols for the T450s laptop. I'm asking this questions becauce I would like to buy a m.2 SSD disk to replace the "too small" 16GB that I have and I would like to know if it's worthwhile buying the Samsung SM951 that supports PCI-E 3.0 x4. Thank you.

A:T450s m.2 SSD

Good day and welcome to the community.
 
Apologies that I can't answer the SATA vs PCI-E portion of your question with any certainty. I can say, though, that the SM951 won't fit physically in your machine. That SSD is a 22x80mm form factor (2280) while your machine takes the 22x42 form factor (2242).
 
Please have a look at your hardware manual:
http://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937.pdf
where manual page 66 describes removal / installation.
 
Then, have a look at the FRU BOM:
http://download.lenovo.com/parts/ThinkPad/t450s_frubom_20150126.pdf
and on the last page you'll see the only factory part listed is the 16GB M.2 2242 SSD normally used for caching (I believe).
 
You should still be able to install a higher capacity 2242 M.2 SSD in that slot, though. The largest M.2 2242 SSD I've seen is also 256GB, but I haven't searched exhaustively.
 
Hope this helps a bit.
Regards.

Hi, Got an issue with a ProBook 470 G3 not booting properly. The battery is charged but the Probook won't boot with the battery in the laptop: it only boots without the battery but with the powercable.  Once booted I can plug the battery in and remove the powercable and it keeps running. But as soon as I want to boot again I need to remove the battery and put the cable back in. It's a brand new laptop and the battery has been replaced by the dealer once already but the issue remains.

Hello, I noticed about six months ago a memory problem was showing in my mini view on my xps 420. I removed the boards and reseated them and the error went away until now. I ran the diagnostics and followed the error code. It said my cmos battery was bad. I changed the battery and now it will not boot. I ran the repair cd with no luck. Can someone offer some suggestions ? Thanks--- Larry D

A:Computer will not boot after cmos battery.

Remove the CMOS battery.
Unplug the power cord.
Press and hold the power button for 10 seconds to fully drain all residual power.
Put the CMOS battery back in, make sure you put it in correctly.
Plug in the power cord.
Power up.

You should get a CMOS configuration error message. Press F2 to go into Setup, load defaults, set date and time and boot options then see if it will boot.

I was working on an old computer for my son today. I forgot my password so I removed the battery to reset everything. When I replaced it the screen stays black. Everything appears to be operating on the inside of the case but my keyboard will not light up and my monitor stays in standby mode. Prior to removing the battery the computer ran fine.
 

A:failed boot after removing battery

That indicates that the computer is not even reaching the POST stage of booting from the BIOS.

What else might you have disturbed while removing the CMOS battery?
Is there a tamper switch on the case that has been triggered? (a "feature" of a few older PCs)?

Is the battery reinstalled in the right manner?
